Abstract
The utility model relates to an energy-saving electric iron. A slight touch conversion switch and a diode are arranged on a handle of an original electric iron; the slight touch conversion switch is provided with three terminals; a live wire is connected with a power terminal; the A end of an output terminal is directly connected with an electric heating wire; and the B end of the output terminal is connected with the diode, and then is connected with the electric heating wire.
Description
Affiliated technical field
The utility model relates to the electrical maintenance field of tool, is specially a kind of energy-saving electric iron.
Background technology
The electric iron structure that uses at present generally is made up of handle, heat radiation cover, soldering tip, heating wire, when full load, when using for a long time, the heating wire of blowing and oxidation solder horn is arranged, and causes depressed phenomenon, and causes the deficiency of energy waste.
Summary of the invention
In order to overcome existing electric iron in full load, when using for a long time, because of the deficiency of blowing heating wire, oxidation solder horn and energy waste phenomenon is arranged, the utility model provides a kind of energy-saving electric iron, and this electric iron can not only prolong its service life, and can also play the effect of energy savings.
The technical scheme that its technical problem that solves the utility model adopts is: original electric iron handle part is installed touched change-over switch and diode, touch change-over switch three binding posts are arranged, live wire connects post with power supply and is connected, output connects post A end and directly links to each other with heating wire, output connects post B end and is connected with diode, links to each other with heating wire again.Its operation principle is: when normally welding, plug is connected the 220V power supply, puts through the A end touching change-over switch, make electric current by touch change-over switch, the input linear flow is gone into heating wire makes it heating, heat is sent to solder horn, normally welded condition.When stopping welding, or short time when stopping, switch to B and hold touching change-over switch, make electric current pass through diode rectifier circuit, 220V voltage is reduced to 99V voltage, to reach the purpose of preheating insulation.When change-over switch once more, voltage can go up to be 220V rapidly, continues welding.
The beneficial effects of the utility model are both to have prolonged the service life of solder horn and heating wire, again energy savings.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 electric iron outline drawing
Fig. 2 electric iron circuit diagram
1. touch change-over switch in Fig. 2, and 2. power supply connects post, and 3. output connects post A end, and 4. output connects post B end, 5. diode, 6. input line, 7. heating wire.
The specific embodiment
In embodiment illustrated in fig. 2, the 220V power supply through power supply connect post (2), touch change-over switch (1), output connects post A end (3), input line (6) flows into heating wire (7) makes it heating, heat is sent to solder horn, is normal welded condition.Touch change-over switch (1) and switch to output and connect post B end (4), make electric current pass through diode (5) rectification circuit, 220V voltage is reduced to 99V voltage, is the preheating insulation state.When touching change-over switch (1) once more, voltage can switch to 220V, continues welding.So not only shorten the preheating time when continuing welding, and, play the service life of prolongation electric iron and the effect of energy savings by diode (5) rectification circuit.
Claims (1)
1. energy-saving electric iron, its handle part is installed and is touched change-over switch and diode, and it is characterized in that: touching change-over switch has three binding posts, live wire connects post with power supply and is connected, output connects post A end and directly links to each other with heating wire, and output connects post B end and is connected with diode, links to each other with heating wire again.
